Unable to post to remote url #2945

I am trying to send data to remote url using the wp_remote_post. I did not set up any permission call back for the code but i get a 403 forbidden error when i click to send form with data to remote url.This is my code;

function register_custom_route(){ register_rest_route( 'silentblast-dashboard/v1', '/getsetting/', array(

array(

'methods' => 'GET',
'callback' => 'retrieve_settings_data',

),

array(
'methods' => 'POST',
'callback' => 'update_settings_data',

)
));

}

function update_settings_data( $request ){

$out = update_option( 'buddy_settings', $request );

$out = get_option( 'buddy_settings' );

return $out ;

}

$remote_url = 'http://localhost/wordpress/wp-json/silentblast- dashboard/v1/getsetting/';

$posts = (array) $posts;

$args = array (

    'method' => 'POST',
    'timeout'     => 45,
    'redirection' => 5,
    'httpversion' => '1.0',
    'blocking'    => true,
    'body'        => $posts,
    'cookies'     => array ()

);

$request = wp_remote_post( $remote_url, $args );
if ( is_wp_error( $request ) ) { $error_message = $request->get_error_message(); echo sprintf( 'Something went wrong: %1s

', $error_message ); }
else {

//echo 'Response:

';

print_r($request);

echo '

}
Why do i get a 403 error when posting data to remote url with code below;

$remote_url = 'http://localhost/wordpress/wp-json/silentblast-dashboard/v1/getsetting/';

$response = wp_remote_get( $url );

$posts = wp_remote_retrieve_body( $response );

$posts = json_decode($posts);

$posts = (array) $posts;

$args = array (

'method' => 'POST',
'timeout' => 45,
'redirection' => 5,
'httpversion' => '1.0',
'blocking' => true,
'body' => $posts,
'cookies' => array ()

);

$request = wp_remote_post( $remote_url, $args );
if ( is_wp_error( $request ) ) { $error_message = $request->get_error_message(); echo sprintf( 'Something went wrong: %1s

', $error_message ); }
else {

//echo 'Response:

';

print_r($request);

echo '

}
